Application June 1, 1949,.Serial No. 96,452 3 Claims. (Ci. 201-55) This invention relatesto a novel arrangement for opening and closing storm windows by raising or lowering the interior house window sash.

It is an object of this invention to provide a mechanism whereby by the raising of the lower window sash in a house or other structure; the storm sash will be simultaneously opened outwardly, and bylowering the lower window sash in combination with the foregoing objectives,

simple, adjustable, regulating. means whereby the degree of closure of the storm sash may be easily,

quickly and accurately adjusted from within the building so as to effect a more perfect seal against drafts and leakages.

Withthe foregoing and otherobjects inview, I have devisedthe construction illustrated in the accompanying drawing forming a part ofthis specification. It is, however, to be understood the invention is not limited to the specific details of construction and arrangement shown, but may embody various changes and" modifications within the scope of. the invention.

in this drawing:

Fig. 1 is a sideelevation partly in section with the storm sash in open position Fig. 2 is a sectional view of- Big. 3 is a sectional view of Fig. 1' at 3 3-;.

Fig. 4 is a side view and section similar to Fig. 1-, but with storm sash in closed position Fig. 5 is another side view and section similar to Fig. 1 with storm sash in open position and showing the storm sash hinged at the top ofthe window frame and both upper andlower window sashin relative position; v

Fig. 6 is asideview of the jamb bracket; and

Fig. Tie a side view partly in section of the spring clip in closed position. I e

The window includes the usual frame l0 comprising the conventionalsill H and runways 8 and 9 for lower sash I2 and upper window sash l3 respectively, formed by jambs or guides Ma,

Nb and I40, is equipped with the conventional storm window sash l5 removably hinged as in Fig. 5; with a pair of conventional hqoks Hi to theupperand-outer portion of the window frame,

and adapted to pivotonsaid hooks and fit within the window frame Hlagainst jamb I la when closed. I

A pair of right angle window brackets H" are attached to each upright end member 18 of" the lower sash frame with screws l9 throughapair of longitudinally spaced holes provided on one side of each of said brackets. The other side of said brackets, transverse to the side attached to the sash, is provided with wide-headed stud 2 -0 riveted or otherwise rigidly connected to said window bracket, as shown in Fig. 2

e A cam-bracket it is attached to each upright side member 15;; of the storm sash. The cam bracket 2i is substantially a right angle bracket provided with a longitudinal cam slot 22: in one side flange and a pair of longitudinal lots tl'a (Fig. 3) in the other side flange or base. The cam bracket is connected with a pair ofv screws 2-!0 through the slots 21- to the interior surface of the opposing uprights I501, of the storm sash (only one upright is shown in the drawing).

The slot 22 incam bracket 2| is preferably inclined, as shown in the drawings, upwardly and inwardly towards the window frame. The slight angle: ofthe slot as illustrated provides moreenicient leverage for the spacer links here inafter described.

A pair of flat spacer links 23- are each provided with two holes, one ateachend. One of the holes is sufiicientl-y' large to fit over the wide head of stud 20 in the window bracket ii. The other hole is of suitable size to receive a stud or .riv-et 24 slidablein thecamslot 22.

Another pair of; spacer links 25 are likewise each provided with apair of holes at each end, one large-enough to fit over a wide head stud 211a attached to' the bracket 25,11ereai-ter more particularl-ydescribed, and the other to engage rivet or stud 24. I

A pair of jamb brackets Ed is provided with a screw receiving hole 21 near one end, a stud receiving hole 28 in the center, and a slot 2!! near the other end, theslot opening at the top to allow engaging and disengaging a. screw 2%. A-wide head-stud orrivet 20a. similar to stud 28' is rigidly attached to the jamb bracket in the center hole 281 The jamb brackets are attached across opposingpairof jambs ledand lib with screws having heads larger than the holes and slotsof the bracket. v The bracket as can then be pivoted on the screw engaging. hole 21' and by means of the slot 29' engage or disengage the other screw 29d. In operating position the slot 29" engages ithe screw. If it is desired to lower tli'enpper sash in the window frame, the link 25' is disco'nnected from bracket 26 and this bracket can then be shifted out of the way by merely swinging it downward, slot 29 disengaging its cooperating screw. Links 23 and 25 are arranged, one on each side of the cam bracket 2!, with their end holes in alignment. The stud or rivet 24 is inserted through said end holes and the slot 22 in the cam bracket, and is of suitable size to slide easily within said slot. The-larger end hole in link 25 is slipped over the wide head of the stud 28a in the jamb bracket and loosely on the stud portion under the head. The larger end hole in link 23 is slipped over the wide head of stud 2G in the window bracket H and bears on the stud under the head. To prevent the linksfrom The device may be easily installed by anyone who can install a storm window, and when once installed can be detached from or attached to a window in a matter of a few seconds when storm windows are removed or replaced in spring or fall.

This device permits a storm window hinged in the customary manner to be opened and closed simply by raising and lowering the bottom sash of the inner window. The arrangement of the links 23 and 25 lock the storm sash in any position against operation from the outside.

Having thus set forth the nature of my invention, I claim:

accidentally disengaging the jamb or window" brackets by reason of the end'holes being larger than the heads of the studs, each link is provided with a spring clip member 36 having an open slot 3! at one end of suitable width to frictionally engage the studs and 26a directly under their wide heads, a longitudinal slot 32 in its approximate center, a wide head rivet or stud 33 connecting said spring clip member to the interior surfaces of the links, and said spring clip members bent to form a handle 34 at the end opposite the open slot 3|. It is preferable that the spring clip member have a slight bend in its flat longitudinal surface to provide spring action for better frictional engagement with the link members.

When the larger end holes in the link members '23 and are placed in position over wide head slide the spring clip members back so that slot 3! disengages studs 28 and 20a thus permitting link members 23 and 25 to slip over the wide headed studs 20 and 20a. and the entire storm sash, together with cam brackets and links, may

be removed by disengaging hooks l6 (Fig. 5).

If a tighter or a looser fit of the storm sash is desired against jamb guide I la when closed, it is only necessary to loosen screws in slots 2m of the cam bracket and slidably raise or lower the brackets accordingly and re-tighten the In operation, an upward movement of lower window sash-l2 will force storm sash l5 outwardly at the pivot on studs 24 within slot 22.

The storm sash cannot be closed except by theaction of the lower sash I2, and the storm sash remains in fixed open position until the lower sash i2 is moved. By lowering lower sash l2 the links 23 and 25 are drawn inwardly andthe storm "sash closed; This arrangement of the links and 'the cam form a toggle action in the slot of the cam 2|, and as window sash I2 is raised this toggle action together with the camming action of stud 24 'in the slot 22 of the cam makes it possible to open and close the storm sash with very little more effort than is required to open the inner window.

It will be understood from the above that this device is designed for windows where storm sash is used for insulating purposes, together with periodic ventilation. It is particularly useful for bedroom, kitchen and bathroom windows, due to the quick and easy way of permitting both window and storm sash to be opened and closed simultaneously.

- l. The combination comprising a window frame,a lower window sash retained within the frame by a plurality of jambs, a storm sash, de-

tachable hinge means for connecting the upper portion of the storm sash to the upper and outer portion of the frame,a pair of window brackets of substantial right angle shape attached one to each upright member of the lower sash, a wide head stud attached to and protruding from one side of each of said brackets, a pair of jamb brackets pivotally mounted one each across theupper sash jambs, said jamb brackets being provided with a wide head protruding stud on one side, a pair'of substantially right angle cam brackets each having an upwardly and inwardly inclined longitudinal cam slot in one side and a pair of longitudinally spaced smaller longitudinal slots in the other side, said cam brackets being attached one on the interior of each of the side uprights of the storm sash with screws through of each pairto the stud of a window bracket.

2. A storm sash pivotally and removably connected with a window frame having a lower sash retained within window jambs attached to the frame and an' adjustable opening and closing mechanism comprising a pair of substantially right angle cam brackets having on one side two longitudinally spaced mounting slots, a screw in each of said slots attaching the brackets, one to each upright memberof the storm sash, each of said cam brackets being further provided on its other side with a longitudinal cam slot inclining upwardly and inwardly from the storm sash,

a pair of window brackets attached to each of the upright members of the lower sash, a pair of jamb brackets pivotally attached one to each pair of sash jambs, said jamb brackets having a mounting hole at one end, a transverse slot in the other end and a wide head stud protruding from one side to the interior of the window frame,

a pair of spacer links on each side of the window, each pair being pivotally connected by a stud through said cam slot, the free ends of one of the links of each pair pivotally connected to one of the window brackets, the free end of the other arm of each pair being pivotally connected to one of the jamb brackets, whereby the action of raising the lower sash will exert an outward motion on the spacer links and open the storm sash and the action of lowering the lower sash will have the opposite effect and close the storm sash.

3. A mechanismof the character described for "opening and closing storm sash windows by the action of raising or lowering the lower sash'in a window frame comprising a pair of cam brackets of substantial right angle shape, one side of each of said brackets being provided with a pair of longitudinally spaced mounting slots adapted to receive screws for attaching the bracket to the storm sash, the transverse side of the brackets being provided with a longitudinal cam slot inclining upwardly and inwardly, a pair of window brackets of substantial right angle shape having holes on one side for receiving screws to mount said brackets to the upright members of a lower sash and the other side of each of said brackets being provided with a headed protruding stud, a pair of jamb brackets each secured to said frame on opposite sides of the window, two pairs of spacer links each pair pivotally connected at the end adjacent the slot with a stud running through the slot, said stud being of suitable size to slide freely within the slot, means pivotally connecting the free end of one of each pair of links to a jamb bracket, and means pivotally connecting the free end of the other link of each pair to a window bracket, whereby raising the lower sash will push the storm sash outwardly and lowering the sash will bring the storm sash inwardly to closed position and the degree of closure of said storm sash may be regulated by loosening the screws which hold the cam brackets to the storm sash and sliding the cam brackets up or down to adjust the degree of closure.-
